Help me diagnose my spark plug

Hi guys, I just took out the No 1 spark plug and took a look at it.
I feel my engine might be running a bit rich but im not sure. Anyone can help me?

When I put the new plug in its socket, the car ran really bad and I figured out the spark wasnt fully screwed… I got really scared lol

Looks like it’s running a bit rich.

Everyone is going to ask.

What carb

EFI

Plus every other question

Engine size

Mods done

But yes it looks like it’s running a bit rich

The nice thing there is no oil on it!

Measure the gap. Looks really small. Looks like the plug is too cold too.
